Slate Shingles Prove To Be A Long-Lasting And Cost-Effective Option

For practical reasons, many builders will install asphalt shingles on the roofs of their new homes. Asphalt shingles are cost-effective, fundamentally quick-and-easy to install, and can last for as long as 20 to 25 years before the roofs need to be replaced. For the same reasons, homeowners will simply continue with asphalt shingles when replacement is needed, particularly when a new roof can be a major expense and its replacement is seldom by choice.

But there is a choice when replacing a roof and, short-term economics aside, this choice can be an exceptionally cost-effective and value-added option for the entire life of your home. This alternative is the installation of slate shingles, a time-tested material that has proven to be:

  • Long-lasting
  • Highly effective
  • Aesthetically pleasing
  • Environmentally-friendly

Slate shingles and slate roofs have their detractors but these are often people who have never owned a home or business with a slate roof and who are merely repeating or reacting to assumptions and hearsay. In fact, they may be heard to say, incorrectly, that no roofing companies even work with slate shingles anymore because these roofs are just too difficult and too expensive to install.

For Avenue Road Roofing, this type of statement could not be farther from the truth. While some roofing companies may shy away from installing slate roofs, Avenue Road Roofing has the knowledge, expertise, and experience that have earned its reputation as the preferred choice for installing and restoring slate roofs in Toronto.

Slate shingles can dramatically enhance the look and longevity of roofs on many types of structures including:

  • Residential properties
  • Commercial buildings
  • Historical and heritage buildings

Make An Informed Decision When Considering The Installation Of Slate Shingles

As would be the case when considering any major investment, the installation of slate shingles requires an in-depth investigation of costs and returns (or savings) from both a short-term and long-term perspective.

With this perspective in mind, the following summary of the advantages and potential disadvantages of slate roofs, better known as the pros and cons, may prove beneficial.
